Solar radio flux recorded by RSTN on 2017-09-06 between 11:55 UT and 12:15 UT from RSTN. This data was recorded at the RSTN node in San Vito, Italy. The solar radio burst of interest occurs at 12:00 UT and shows a large enhancement is the microwave band (~1 GHz); the frequencies of which are used for aviation communication and navigation. Sato et al. (2019) investigated the impact this solar radio burst had on GNSS applications. Note that 1 sfu = 10⁻²² W m⁻² Hz⁻¹.
